Document Type and Number:
WIPO Patent Application WO/2018/174075
Kind Code:
A1
Abstract:
[Problem] The objective of the present invention is to provide a fluidized bed reactor capable of more efficiently mixing a solid raw material compared to prior art, and capable of efficiently producing a reaction product at a given level or higher. A production method for a chlorinated polyvinyl chloride resin is also provided. [Solution] The fluidized bed reactor comprises a reactor that houses a solid raw material in a powdered or granular state, wherein a gas is supplied to said reactor loaded with said solid raw material, and the solid raw material is fluidized by means of the gas while undergoing a reaction with the gas, in order to obtain the reaction product. The fluidized bed reactor includes a light-emitting member and a temperature adjustment member, wherein the light-emitting member has a rod-shaped section on the light-emitting side which is disposed inside the reactor and irradiates the solid raw material with light, and the temperature adjustment member has a rod-shaped section on the adjustment side which is disposed inside the reactor and adjusts the temperature of the solid raw material. Where the rod-shaped section on the light-emitting side adjoins the rod-shaped section on the adjustment side, the outer peripheral surfaces of said sections have a shortest distance of 1.9 cm or greater.
